Faster, lighter, smaller Touch-sensitive screen and the most long battery life-span of colored liquid crystal of maximum on the market The fastest analysis Strongest characteristic and optimal reliability

The instrument company of Oxford introduces handheld X-ray fluorescence spectrometer of new the most proudly – -X-MET7000, it is faster, lighter, smaller. Only need to press a button, it can analyze, determine and screen materials more fast. Have new appearances, bring the feeling of Singapore, fast user interface, strong reporting system, and a whole day -long electric quantity, these characteristics let you finish the material analysis easily.

But the design of X-MET7000 reliability certification, old and useless metal sorting and analytic professional of precious metal for engaged in the metallic materialing specially, totally meet the requirements for high precision. The X-MET7000 offer the intersection of calibrate and bag of apolegamy, suitable for various application that material screen.

This analysis meter can be flexible to choose the analytical method to solve the most thorny application problem. It has assembled the Read more

Accompanied by in the development with fast electron technology, the main forces that the increasingly many person added the electron and developed. In the course of studying electron technology and researching and developing the project, it is unavoidable to use some instruments to avoid, such as multimeter, ondoscope,etc., but to some amateur fans, a digital oscilloscope is the comparison ” Luxurious” used after an attribute. Originally design the digital oscilloscope introduced, because it has low cost, makes the simple, higher advantage of survey accuracy, have met this part of people’s demands exactly. Produce, show wave apparatus to be simple, if you want to produce, it offers high analog input to be difficult in ondoscope of bandwidth. The choice of the main device is the key to realizing design object of the bandwidth of high analog input. This selected works are used C8051F020 one-chip computer as CPU, it has 51 simple kernels and I/ O abundant resources. A/ D chooses 8 high-speed A/D converters TDA8703, the highest sampling rate is 40 Msps. In addition, adopt dual-ported FIFO-IDT7202LA-12, it is a dual-ported memorizer of first-in Read more

The top in the rate of turning the rotational speed into rolling rocket projectile is a response element, its function is to measure the yaw angle appearing in the flight course of the rocket projectile, the yaw angle solve, charge calculation of module, start control device actuating mechanism, carry on attitude control, thus achieve the goal of revising yaw. But the top is the disposable products, it is idle in the course of developing and testing, so need to imitate the gyro signal. The result revised as to yaw needs to judge too, see whether it keeps the same with ideal control result, exist and advance or the hysteresis. So it is necessary to develop an automatic tester to test, besides the above two important respects, develop requirement and test and require the content in need of finding of this tester to have two-shot power in foundation, control device sequence, main engine internal resistance test, attitude control engine internal resistance test.

This test system adopts the embedded computer PC/104, PC/104 and PC/AT architecture is fully compatible, the magnitude has 90mmX96mm only, but it nearly integrates all functions of the ordinary Read more

When function to carry on hardware design debug, to it programmes and then ability to be a key advantage FPGA. When CPLD and FPGA use in early period, if discover and can’t work to design normally, the engineer uses ” debug the hook ” Method. The signal will be guided to the pin within FPGA that will be observed first, then catch the data with the external logic analyzer. But when increasing in complexity designed, this method is no longer suitable, among them there are several reasons. First, because the function of FPGA has increased, the pin number of the device increases slowly. So, can reduce with the rate to I/O of logic, see Fig. 1. In addition, when the design is very complicated, there are only several vacant pins after usually finishing the design, or does not have vacant pin that can be used for debugging at all.

Pursue LUT of 1 Lattice FPGA / can use I/O

Second, the complexity designed now often needs to observe a lot of signals, Read more

IVR system Interactive Voice Response ,Namely interactive voice response system, it is applied to the call center Call Center ,In order to improve and call out the quality of the service, lighten the working strength of the attendant and save the expenses, it is the important door where the call center realized human-computer interaction, in the traditional IVR system, users and the mutual way of system are keyboards phoned. Usually, users will hear associated voice prompt menu after entering IVR system, according to the needs of one’s own one, can push the associated key set on the keyboard. The system conveys users’ request to the system at the same time through the key that DTMF signal transmission users pushed, thus touch off the associated voice messaging. However, the traditional telephone can only convey very limited number of figures and symbol key sets through DTMF signal. This makes the mutual interfaces of users and the system receive very great restriction, just make the information inquiry range of IVR system quite narrow at the same time, users will feel a great deal of inconvenience during in-service use.

NI has offered the high-speed, flexible, rigorous RF hardware, and match the powerful NI LabVIEW software, in order to meet the demand of the domain of wireless communication with rapid change, and run through from designing, proving to all projects design phase for production.

In order to meet the developing communication standard, LabVIEW graphical design software possesses many kinds of tools, can direct against standard and self-defining figure and analog modulation format, finish production of the signal, analysis, revealing and dealing with,etc..

The engineer carries on integration of LabVIEW and PXI RF modularization instrument in the test system, hope to reach more high flexibility and characteristic. This kind integrates and the high-performance measuring system, possess high grade timing, synchronous function and latest computer technology, can offer the Read more

All high speed real-time digital oscilloscopes adopt various digital signal processing techniques DSP at present . Some engineers worry using the software to filter and may tally with actual signal the data waveform that is gathered. However, what the primitive waveform that the ondoscope catches may not show is real input signal, the ondoscope was caught ” Primitive” Having included the distorted result in the undulate data, this was caused by the forward end hardware electric-wave filter of the ondoscope. In ideal cases, quick sampling rate, perfect smooth Frequency Response FR, linear phase response, there are no bottom noise and bandwidth are high that there are the real time oscilloscopes limitlessly. But in the actual environment, the ondoscope has hardwares that was limited, this kind of restriction has produced the error. DSP filter technique can correct the error that the hardware causes to a certain extent finally, improve survey accuracy, strengthening reveals quality.

Commonly used DSP filter technique is the following five in characteristic at present more high real time oscilloscope:

Positioning and relevant the service finds quite abundant application mode and prospect in handheld devices rapidly, user’s reliance locating service of multi-place more and more too. How to find your seat, its technological core and global positioning system GPS accurately Closely bound up. GPS technology costs hundreds of millions of dollars, is made up by at least 24 satellites according to particular orbital motion, the arbitrary position on the earth, can all be covered by at least 4 satellites.

Each satellite sends a message to the earth in totally identical time. GPS receiver catches 4 groups of signals from satellite, is based on the difference of arrival time between 4 groups of signals, GPS receiver can obtain rigorous longitude, latitude and height above sea level. As combining the information with map database, you can get the rigorous place information. The procedure function as navigating, in starting point and final position that you appoint to navigate, the apparatus based on GPS function can offer the route to guide, including the concrete route name, how to turn and predict arrival time.
